Beginning from Hwy 20 along the Pacific Crest Trail, this route is the easiest one up to the top of Three Fingered Jack. From the Pacific Crest Trail is a climber's trail that leads toward the south ridge saddle. Along the ridge you will need to scramble. Below the summit, a gendarme or spiked pinnacle, blocks the way. You will need to ascend on a narrow, exposed ledge called "The Crawl" on the east around the gendarme to reach the summit pinnacle. To make it to the summit, there is a concave wall and shallow chimney that allow access. Equipment includes: rope, chocks and slings, and helmet.
